Best diagnostic method is dual head gauges. balanced pressure between low and high side in the off position is aroung 90 lbs. running low pressure is 20-40 lbs and high pressure 160-200, is the compressior not coming on? does it stay on, or click on and off. either might mean the freon level is low. try unplugging the low pressure switch on the low side supply line and shorting the pigtail wires together with a paper clip. does the compressor stay on now? if so and the air is warm or cool, freon is low. if the air is cold that switch is bad. if compressor still won't come on the list of possibilities grows longer: compressor, comp fan clutch, AC relay, restriction at several places... repair shop time...

Air conditioning system, when you turn on the air conditioner the drivers side blows cold air and the passengers side blows hot air? What causes this problem?


The most common cause of this is that you have a stuck air temperature control blend door, this can be a motor actuator issue or a jammed door or both (common). To replace both parts you will need to completely remove the dash from the car to access the blend door.

My air condition only blows out cold air not hot


Turn your air conditioner OFF and turn your heater ON. Air conditioners were designed to blow out one temperature of air... COLD.

Air conditioning blows hot and cold air


You will need to know if the compressor is working when it blows hot air to proceed. It could be an electrical problem, a blend door problem, or the a/c clutch on the compressor.

The air conditioning system will only blow cold air. Regardless of the mode, I can only get cold air. Can you give me an idea on how to fix the problem? Thanks Don 615-653-3834 drcamp117@comcast.net


The air conditioning is supposed to blow only cold air. Are you trying to get the heater to blow hot air? Make sure the temperature selector is in the hot position.

I know in my mother's 04 liberty she had the same problem. Only would kick in on high. It was the selector that was bad. Its not to big of a problem unless it bothers you.
Good luck,
